What are the ideal rates/percentage for financial ratios like Debt Equity Ratio, Current ratio, DSCR, TOL/TNW, ROCE, ROE, etc...?

All the above mentioned ratios are ideal. Its where these are used to analyse one's company's balance sheet. D/E Ratio is while considering a new finance exposure by a bank or financial institution while current ratio is looked into during financing short term loans, viz., cash credit, financing on stock, etc. Also it maybe noted that DSCR, TOL/TLN, ROCE ROE is very important during financing a new project loan. And last ROE is  helps in investing in equity.

debt equity should below405, current ratio is11, ROCE and ROE should at least30% and above
