| Your pot is still large for the this size Dendrobium. I would leave it in the same pot.
By the growth pattern it looks like two plants in the same pot. This is not important.
Unless the medium is going bad it is best to leave everything as it is.
There is no need to cut bare canes as they are beneficial to the plant supplying food and water to the plant if needed. This is not an exceptional amount of bare canes for a Dendrobium.
The bent canes can be straightened and staked. Take your time. You do not need to straighten it all in one shot. Put a stake in the pot and bend the cane until the resistance increases and tie it off at this point. In a couple of days the cane will have grown to accept this bend as normal. Now bend it some more. Continue until you can tie the cane completely from the base to the top of the stake. You will probably need to tie it in about 4 places. Dendrobium quickly form themselves to the new shape.
