Lots of good advice above. 1:1s are a must. How often you do them is up to you and depends on what else is going on. I used to do 1:1s weekly, in a room. That way they each had my full attention and I theirs. Guess what? I heard, third hand, that one of the team interpreted this as meaning that I was "giving different people different messages". She preferred "full transparency" ie all info should be shared with everyone at the same time ....
I also did daily 15-minute team meetings, at which everyone had an equal chance to share what they were working on, ak for help, offer help, make suggestions, celebrate good stuff, raise issues, ask questions. I still did the 1:1s as well though!
Assuming your team has clear targets, what can work well is getting them together and list, as a team, 'what works well'; then what would be 'even better if' (these are the things that need to change). Give yourselves credit for the 'what works well' - you don't want to lose what works!
Now prioritise the 'even better ifs' by thinking what impact each would make.
Next draw 3 concentric circles. The inner one is for things the team can change, the middle one is for things the team can change with help from outwith the team, and the outer one is things that can't be changed (eg external deadlines).
Hopefully the key priorities are mainly things the team can change, or at least influence. What you need next is an action plan with owners and deadlines.
Put it all on display, so that you can hold yourselves accountable, as a team.
Review this periodically, say once a month or quarter.
You will learn a lot from the team's approach to this activity and the follow-up.
