hello,

there are some expensive weapons which has a orange icon. i think because they have a special attribute but i don't have a clue what that does.

thanks in advance

It is but it's not worth the meseta generally speaking. The ability that it has is one that boosts the damage of Just Attacks by 5%.
EDIT: Actually, my bad, its just 3% not 5%, then no, it's not better.

Those are weapons with their Weapon Potential ability unlocked by getting it to +10, spending Photon Spheres, and setting it back down to +0 again.

Some are worth it, some aren't. Lambda Legzaga is basically the 2nd best Twin Dagger since it matches S-ATK with Blade Dance and has Immediate Strike (the gold WP ability) on top of that. Is it worth the actual meseta cost vs getting your own and grinding it / getting better abilities? Probably not. Especially that one since the abilities are meh.
