Is a 5x5 big enough for 6 plant flower?

Hello everyone, at the moment I have a 2x4 tent with a mars hydro 300watt light and 2 plants in 7 gallon grow bags in soil. I also have a 5x5 with a 800 watt mars hydro light with 4 plants in 5 gallon dwc containers (hydro). I plan on making my 2x4 a veg tent and my 5x5 a flower tent. My question is can I move all those plants to flower in the 5x5? Will that be enough space for 4 plants in 5 gallon containers and 2 plants in 7 gallon? I want to veg in the 2x4 about a month before my harvest so I can rotate plants from veg to flower and harvest around every 60 days.
Please share your thoughts , thanks everyone !

definitely going to be crowded with that many plants but I have seen people on this forum do it…
