Well, no chip should get

Well, no chip should get "burn you" hot, so there's a big chance of the 8502 being shot.
What kind of equipment do you have access to? Do you have an oscilloscope?  If so, you can probe the address-lines of the 8502 and see if there's any activity. If there isn't, either the 8502 is shot, or there's something holding them high or low..
When you say "I do have clock signals and 5v votage on the chips.", which chips are you talking about?
As for getting the chips out, you can either get a solder-sucker like this: https://amzn.com/B00BG62F6E
If you see yourself doing this more than once, and have an extra six bucks to spend, I'd go for something like a solder-sucker with a heater: https://amzn.com/B00B88FRME

I have checked for clock
The solder sucker I have has
Yea, it will look like they

Yea, it will look like they're soldered on both sides. It's from the wave-soldering process, and the solder gets "sucked" up through the holes because of the capillary forces. It's definitely possible to desolder them from the back of the board only. It's the way I do it. Thats how I know.
You seem to have a good routine, with adding new solder and fluxing it as well, so you're on the right track. Just keep trying. A common mistake is to not heat the pin long enough. My weak-ass desolderer (actually, the exact same one I linked to before) needs me to hold it on the pin for a good three seconds before I can suck out all of the solder.
As for the chips where the pins are bent, the technique I usually use is to take my regular soldering-iron, melt the solder, and bend the pin with the tip of the soldering-iron whilst the solder is wet. This isn't super-nice to the tip, so don't use your best one. :)
I don't know of any hacky ways to check the 8502 or Z80 out-of-socket, but that doesn't say much. I'm sure some people on here knows some neat ways of diagnosing them by measuring their resistance or somethings. If you have a clock generator and some EE know-how, you could build the support circuitry needed to make it free-run on a breadboard in a few minutes. A bit overkill though..
You never said how you checked the clock-signals. If you have an oscilloscope, check the reset-line and address-lines on the 8502 and Z80 to see if there's life in them.

yes I forgot I have a scope
The PLA could definitely have

The PLA could definitely have something to do with the whole "computer not working" part.
The PLA is responsible for mapping in the different ROMs, so that the 8502 have something sensible to execute. However, as the state of the machine is, many things are possible suspects.
The more methodical approach to this is to verify the (at least basic) functionality of each subsystem. Well, at least that's my approach..
If you want to look at the PLA, you could look at the ROM1-ROM4 signals out from the PLA. I'm a bit out of my water here, but I belive only one of these should be low at any time.
HOWEVER.. If the outputs from the PLA doesn't "make sense", it doesn't mean that the PLA is broken. The PLA acts on what it sees on the address-bus (and a few other pins), so if the 8502 is dead, the PLA won't act normally.

what i did sofar
resoldered different 8502 and z80
