Answer 1

Blaziken: Choose Overheat... Bulk up instead of slash...

Flygon: Not bad

Walrein: Looks good!

Aggron: SolarBeam sucks. Just go with ThunderPunch.

Metagross: Pretty good....

Starmie: Surf instead of Waterfall...

Hope this helps!

Note that it's an Emerald team - the Physical-Special is different, so Blaze Kick is Special, ThunderPunch is special, and Crunch is Special too.

Answer 2

You have a well-balanced team.
I can recommend a few tweaks though.

Blaziken
Keep Overheat with White Herb
Replace Slash with something more benificial (Bulk Up, Counter)

Flygon (nice moveset!)
Just replace Dragon Claw with Ice Beam (Ice Beam covers more types, kills 4x Dragons, and you can kill Kingdra with Earthquake anyway

Walrein
Just change the nature to Timid

Aggron
Swap Aerial Ace for Rest/Iron Defense because Earthquake does more damage than super eff. Aerial Ace anyway
Keep Iron Tail
Switch Focus Band with Quick Claw

Metagross
Switch Shadow Ball with Light Screen

Starmie
Go with Surf instead of Waterfall

Overall, you have an excellent team.
Just do the little corrections I gave you and you will kick some major butt!
Have fun!

Aggron doesn't get STAB on Earthquake due to him being a Rock/Steel type, so the damage would be 100, not 120 like a super effective Ace, so Ace would be more powerful in this situation, not earthquake.
