The red highlighted parts of the model mean that the area needs support material (as they exceed the minimum support overhang angle). So yes, it looks like the 'rope' sections and bottom section will require supports. Cura can place these automatically.
If you want to use support more efficiently, you can use features such as conical support or gradual support.
Hope this helps.

Set top thickness and infill density to 0. That will give you an open box with just bottom and walls.
Layer settings and wall thickness is something you need to find out based on your requirements and printer quality.
When I print concept models just for "show & tell" I ususally print with 0,3 layer height and 0,8 wall with 5-10 % infill.
Models for use, like tools and parts for testing usually 0,1 mm layer height and 3 mm wall.

Thanks for your answer AndersK. I will set infill and top thickness to 0 density. I have few more questions regarding support. so I have attached pictures pf my models for that. my base surface of model is very uneven and have embossed pattern on it. Will it need support on bottom?. Also ropes shows a little red spots from lower side. if I put support it shows from bottom to robes. which cost a lot of filament and time. how can I reduce support to save filament and time ? does this another small plate object can be print without support too ?
