HELP!!! Some emergencies but overall it's getting better

[Roey.P.]

everybody.
So, currently I have a purple dendrobium, three phalaenopsis (white red dot, yellow), black leaves jewel orchid, and one white phalaenopsis I saved.
And especially for him I'm here I have a shop near my house of renting apartments fill the houses with bloom orchids which they Drowned in jars of water without holes (because they thought it pretty that way) , so the plants quickly lose flowers and then are thrown in the trash . That hurt the guy so I decided to rebuild it because not like the others he still had a chance. I nicked stems with disinfectant and cinnamon. And started to water once a week / two weeks by the weather. We are still flowering season and perhaps it will have more flowering stems.
Now I saw that the plant is trying to create stems (include photos) that go from the root and not the base of the plant so are they roots or can they be flower spike?
So the questions are:
1) Is there a situation that it is flowering spikes?
2) Should I pot the plant in a new platform, although not finished blooming season because there are many rotten stems (no mold or fungus) or wait?
3) One of the phalaenopsis have a green leave with red dot on it should I worry about that? (It's not yellow so it's not a sunburn right?)
Please help me save the plant.
In addition, if you have any comments about the rest of the plants I'd love more.
