do u guys think that maybe i can have a group of Neon Tetras? Maybe 6
6 neons would be fine for such a tank, although they would thrive better in an established tank, if the tank is under 3months old, especially if its not cycled or going through a cycle, they probably wouldn't fare that well in the tank as they are very sensitive to water quality conditions (which are not stable in young tank set ups).

A 10g will support around 40-50 1-1 1/2" fish if well aereated and filtered. Your main limit is place by the lack of a heater. If the tank is in an area that has a stable temp in the mid 70s then many of the smaller tetras will work though neons can be touchy at that temp. range. A mix of 6 pygmy cories (C. pygmaeus) or dwarf black diamond cories (C. hastatus), together with 6-8 glo-lights, 6-8 blue tetras, and 6-8 lemon tetras, with up to around 12-18 ghost shrimp will work in a 10g as long as you give it lots of multilayered strsuch as bushy plants, artificial will be okay.
40-50 in a 10gal fish sounds very crowded to me, in small tanks you don't just have to worry about over-stocking, over-crowding is a very real problem too and can be just as bad. If your tank is over-crowded, the fish will feel stressed and will become more vunerable to diseases and parasites, and treating diseases/parasites in an over-crowded tank can be very difficult indeed.
Not just that, but the average 9-10gallon tank filter would not be able to cope with the bioload of 40-50 fish.
If the tank has a lot of filtration and healthy planting and is fully established, personally i would stick to no more than 2 types of shoaling fish in shoals of 5-6 fish each, a few extra top or middle dwelling fish, and a few types of bottom dwelling fish numbering no more than 5.
So much depends on the exact type of fish though and the exact type of environment in the tank, its very hard to apply guides like the 1-2inch of fish per gal rule of thumb etc to stocking with any real degree of success etc.
The tank is actually closer to 9 US gallons;
Dimensions 48 x 30 x 25cm/19" x 12" x 10 Surface area 0.14 sqm/1.51 sq ft/ inches sq in Volume 37 l./8 gal. (9.77 US gal.) Probable volume 33 l./7 gal. (9 US gal.)
'cos its a long 9gal though, i would still treat it like a 10gal in certain respects.
A soft sand or very small fine rounded gravel substrate, some planting and decor to create hiding places, is important for keeping fish like corys healthy and happy.
