Sally-light-foot crab
Grapsus albolineatus
Family Grapsidae
The first crab (Grapsidae), the molting skin seems from Grapsus albolineatus
The second crab (Portunidae) is similar to Thalamita crenata

It's a little late but i confirm Grapsus albonineatus and Thalamita sp. (not sure for crenata)..
2-5 looks close to Charybdis (Charybdis) natator (Herbst, 1794) - PORTUNIDAE and 1, 6-9 is Graspus sp. - GRAPSIDAEas pointed out by other colleagues
You can ask directly from my colleague Dr. Owfi ([email protected]). He is an specialist in this field.
