this old main panel has double & triple tap

[Ben Im]

As you see, 40amp breaker has 2,3 lines together red lines go to condenser unit but I don't know the blacks for.
Any other violations you guys see in this panel?

Solid aluminum branch wiring is problematic. Many insurers have a big problem with it as the connections at splices, receptacles and switches are seldom done correctly and loose connections in AL wiring have been proven to be the cause of many residential fires.
The AL wire to the 40 amp breaker is way undersized.
The double and triple tap is obviously wrong, doubly wrong because mixing CU and AL wires.
No antioxidant paste on AL wiring that I can see.
Push to reset breakers are often an issue because of age, failure to reset. That isn't a Bulldog panel is it? Looks to be some other brand, maybe just in a different configuration that I haven't seen.

this is not the same figure with Bulldog panel that I 've seen before.

there is some questions?

1. why I can not see any wire to main breaker?
2. What should I tell about Al. wiring? - hundreds of this condominium (1969 build) complex are all Al. wiring. Replace with CU.? Just watch out?
Maybe my client will live in this home without peace of mind then,,,

What should you tell about AL wiring?
1. Your insurer may be among those who will refuse to cover the home at all or until proper repairs are made.
2. AL wiring can be a fire hazard if the original installation was not done well. (from the photos this could very well be an issue in your case)
3. AL wiring can be a hazard if improper repairs have been made. (again very likely from the photos)
4. Al wiring can be a hazard if improper switches and receptacles were used at the original installation or in subsequent repairs.
And the list goes on and on. Try http://inspectapedia.com/aluminum/aluminum.htm for some info on AL wiring, check the Mike Holt site for further, study up on the issue and be prepared to see this frequently.

Your photos show a host of issues in the panel alone, it is very likely that other problems exist throughout. Undersized wires, double and triple taps, crowded panel with no room for expansion, grounds and neutrals on the same bar in a panel that most likely is not the service equipment. More than enough problems and issues to recommend repairs by a licensed and competent electrical contractor. Be sure to include something along the lines of "other issues will be brought to light as repairs are made". Document the issues, call for repairs and move on, do not try to recommend the manner of repairs.

are you a home inspector--if so you don't know about aluminum wiring-mis gauged wire and double taps==if you are you should know this like why the sky gets dark at night

Google search Aluminum wiring, write a short story about it and give that to your client. The connections at all fixtures need to be inspected and repaired as needed. No doubt the guy that worked in this panel doesn't have a clue, so all the wiring needs to be checked for fire hazards.

If this is an example of wiring in a condo building, yes everybody in the condo should have their panels inspected for fire hazards.

Due to temperature change, vibration, and several other causes it is critical that any AL installation is done properly in the beginning and periodic inspection, re-torquing to specifications, and maintenance is performed. For this matter, it is a very good idea do do this with a copper installation too. My rule of thumb is every spring with changing out the detector batteries but be absolutely sure you know about all preliminary safety precautions or please call on a qualified person.
