Ham legion is the best between legion and tengu, because its the only viable damage profile

lolno. Angels are 2nd weakest to kinetic. Tengu has a bonus to kinetic. Tengu is excellent in most situations and these angel plexes are no exception, unless for some reason you are only getting 350 raw dps or something. I won't comment on the HAM legion, it should probably work but the stasis towers will make you a sad panda.

Angels have no 6/10, they have a unrated plex with a guaranteed escalation that drops similar loot. Beware the neutralizer sentry III's in part 2.

machariel/cnr/golem will of course work but they're not necessary for soloing or clearing the site quickly.

I'm not going to post my own fit, I don't think it would be that helpful to you. It mostly depends on what kind of shield booster you want to use, how much you want to spend, and how much your prioritize dps, burst tanking, capacitor, and frig-hitting-ability. Here is an example of nearly fully t2 fit that should be able to clear the angel 5/10 and 7/10 with no problems.

with lvl 5's and no implants this basic cheap fit does 601 dps, which is way more than enough to kill top-tier npc battleships at a good pace. Most people elect to drop a few hundred mil for some nice fittings, getting a much stronger as well as more sustainable tank, more dps, and using less cpu allowing a switch to the dissolution sequencer. The only weakness is with a t2 medium booster, your burst tank is kind of low and you rely a bit more on your speed to reduce your damage, but that's what overloading is for (plus you can 1-shot any stasis tower within your lock range). Then again, if you spend a little bit of isk you can also get do all this with a mwd and the agility subsystem, which is nice for lowsec work.
