Hi @gurleenm
For demo purposes i have created a sample sharepoint list which has Name and EmailID of persons whom email need to be sent like below

Now the flow should be designed like below:
Step1: Use Get items to retrive Items from SharePoint List

Step2: To get the list of email ids from the sharepoint list as an array, use select action to select EmailID from values dynamic content like below

Step 3: To Join the email ids with ; , as the semicolon is used as delimiter for sending single email to multiple person at same use Join action to join the array obtained from Step2 with ; delimiter like below.

Step 4: Now use send email action email from Shared email Box like below

Hope this helps !
