That is difficult to say; we would need photographs of some details (e.g. the pelvic fins of the specimen in photograph 1).
Photograph 2 represents an eleotrid (with separate pelvic fins), photograph 3 a gobiid.
Please also provide information on the collecting locality and the habitat.
Hello Dear researcher
You must provide different views of the image so that the number of ventral and dorsal fin is also morphologically distinct.
Morphometric and meristic identification information is required.
The file will be sent to you. I hope to be able to help you.
Also a site that is key to identify the species listed below.

Sir Ronald Fricke, it was collected from estuarine benthic zone salinity about 20-25ppt
I suppose you collected the specimens in SW India?
Please provide some additional photographs; for each species we need at least a lateral and a ventral view.
Sir i have many specimens, so i will sent to you wen i get particular one here
Specimen 1
Specimen 2 is most probably Trypauchen vagina (Bloch & Schneider 1801) (subfamily Amblyopinae, family Gobiidae).
Alternatively, Caragobius urolepis (Bleeker 1852) may be found in India, but that species has a different head shape and a larger pelvic disc.
Specimen 1 is more difficult to identify; I would need to count dorsal and anal fin rays, scales on head and body, and probably also need to see papillae on the head.
I don't think it could be Eugnathogobius variegatus (formerly Calamiana variegata), which has a different head shape and different colour pattern (and furthermore does not occur in India); see the paper of Larson (1999) for a redescription of that species:
Larson, H. K. 1999 Allocation to Calamiana and redescription of the fish species Apocryptes variegatus and Vaimosa mindora (Gobioidei: Gobiidae: Gobionellinae) with description of a new species. Raffles Bulletin of Zoology v. 47 (no. 1): 257-281.
I think it is correct, Trypauchen vagina. I am attaching picture of head postion for more details
Not absolutely sure, but specimen 1 (the first in your attachment) could be Glossogobius biocellatus.
Specimen 2: Acentrogobius sp.
Third specimen: still uncertain
I think the three species below review. May have similarities. Especially first.
Trypauchen vagina
Taenioides gracilis
Trypauchen pelaeos
Sir, Can you help me to findout species of Specimen 2: Acentrogobius sp. and and spoecimen 3?
The problem is that I need additional data for a better identification, including prevomerine dentition, details of the opercle and preopercle, and head papillae.
