Hi and welcome aboard,
Those readings are high and not desirable. It looks like your diet needs an overhaul.
You are already learning from your meter that certain foods are not wise choices for T2 diabetics, such as potatoes and fruit.
If you organise yourself properly with your testing, you will learn a lot more. Test before you eat and again 2 hours after first bite. Keep a food diary including all ingredients and portion sizes and record your before and after levels alongside. Look at the amount of rise from before to after - that is the important figure initially. It needs to be under 2mmol/l and preferably less. If it is more than 2mmol/l there are too many carbs in that meal which need reducing in portion size or eliminating. This is called eating to your meter, and will help you enormously.
Have a look at
https://www.dietdoctor.com/low-carb/foods#foodlist for some idea on the types of food to eat to bring your levels down and keep them down. It also lists foods to avoid, and there are some recipes.

@daisy1 who will come along and post some very useful information. Meanwhile have a good read round and ask as many questions as you like.
